Driving Assistance System Risk Force Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driving assistance systems fail to effectively convey different levels of risk to drivers, making it difficult for operators to recognize and respond appropriately to varying risks while driving, as they rely on complex haptic signals from multiple vehicle components.
Innovation Solution
A system that uses a detection assembly to gather environmental data and a risk potential calculation device to classify risk levels, transmitting reaction forces through operator-controlled devices like the accelerator pedal and pressing forces through vehicle equipment like the driver's seat, allowing for intuitive risk communication based on the driver's operation state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple different pressing forces are transmitted from different portions of the driver's seat to convey various risk levels, then information conveyance is improved, but device complexity and driver confusion increase
Solution Approach 1:
The patent segments risk information conveyance into two distinct channels: reaction force through the accelerator pedal for high-risk situations, and pressing force through the driver's seat for low-risk situations. This segmentation allows each component to have a specialized function, reducing overall system complexity while maintaining comprehensive risk communication capability.
Solution Approach 2:
Different portions of the vehicle interface are assigned different functions based on their characteristics. The accelerator pedal specifically conveys high-risk information through reaction force, while the driver's seat conveys low-risk information through pressing force. This local quality assignment optimizes information conveyance efficiency for each component.
2Reliability
If reaction force is transmitted through the accelerator pedal for high risk, then appropriate driving response is prompted, but driver operation complexity increases
Solution Approach 1:
The accelerator pedal serves dual functions: it remains the primary control device for acceleration while simultaneously conveying high-risk information through reaction force. This self-service approach eliminates the need for separate warning devices, maintaining operational simplicity while enhancing safety communication.
3Ease of operation
If pressing force is transmitted through the driver's seat for low risk, then risk information is conveyed without interfering with control operations, but information intensity is reduced
Solution Approach 1:
The system segments risk levels into high-risk (conveyed via accelerator pedal reaction force) and low-risk (conveyed via driver's seat pressing force). This segmentation ensures that low-risk information is conveyed through the seat without interfering with accelerator pedal operations, while high-risk information receives more intensive communication through the control device itself.

AI summary
A driving assisting system for assisting a driver in operating a vehicle. The system includes a detection assembly configured to obtain environment information related to an environment around the vehicle. A risk potential calculation device is provided to calculate risk potential associated with the vehicle based on the environment information. A controller causes a reaction force determined based on the calculated risk potential to be transmitted to the driver via an operator controlled input device in response to the calculated risk potential being a first type of risk potential, and causes a pressure force determined based on the calculated risk potential to be transmitted to the driver via equipment of the vehicle in response to the calculated risk potential being a second type of risk potential. The operator controlled input device is used by the driver to control the driving of the vehicle, and the equipment is different from the operator controlled input device.
